Improvements in Multiple Drop-Feed Apparatus for Liquids, of which the following is a specification.

My invention relates to drop-feed apparatus for liquids, and more particularly to that kind of such apparatus in which two or more liquids of different specific gravities or of otherwise ,different characteristics are contained each in its own chamber and are fed therefrom each independently of the other in measured or determinate quantity, and preferably in visible drops. Such an apparatus is useful in a variety of connectionsfor example, as an oiler to feed lubricants of different kinds to engines in cases where one kind of lubricant is required for the cylinder and another kind for the bearings, as an instrument in surgery for the administration of different kinds of anesthetics, &c. Y

The object of the invention is tomake such apparatus simple and compact in construction and eflicient in operation; and the main characteristic of the invention is that the apparatus comprises separate and distinct superposed vessels or chambers for holding the dierent liquids, the vessel above discharging its contents through a conduit which passes through, but does not communicate with, the vessel or vessels below.

The invention will first be described in its structural details in connection with the accompanying drawin s, forming part of this specification, and will then be more particularly pointed out in the claim.

In the drawings, Figure l is a vertical aXi, al section of the apparatus in its preferred form. Fig. 2 is a like section, partly in elevation, of a modification. Fig. 3 is a like section, in a plane at right angles to the plane of section in Fig. l, of still another modification.

Similar letters of reference indicate corresponding parts in all the figures.

A is the body of a vessel of any suitable form, preferably of cylinder shape, and of any suitable material, preferably glass, provided at the lower end with a metallic bottom piece B, in which the glass sits, a cork washer C or a washer of other suitable material being interposed between the glass and the metallic bottom B. At its upper end the vglass body A is provided with ametallic cap D and with ano ther interposed washer E to make a tight joint between the top of the glass and its metallic cap. The cap is providedwith an opening F. The opening F is closed by means of a damper in the shape of a screwthreaded cap G, which screws upon a like screw-threaded part of the cap D and is provided with an opening H. When cap G is turned so that the two openings F and H register, the iiuid to be contained in the vessel A may be poured in through these openings. When, on the other hand, the cap'G is rotated sufliciently to throw the opening H out of register with opening F, the latter will be covered by the blank surface of cap G and the vessel A will be closed.

In the center of the bottom piece B is screwed a tube I, which passes through the glass A and the caps D and G. The protruding upper end of the tube is threaded for the reception of a lock-nut K. By screwing this lock-nut against the projecting nipple L of cap D the bottom B and the cap D will be drawn tight against the washers at the top and bottom of the glass A, and a Huid-tight joint will be made at those points. It will be noted that there is no communication between the tube I and the vessel A-that is, nothing can pass from the tube I into vessel A or from this vessel into tube I.

Into the sides of bottom B are screwed the chambers M, having direct communication with the interior of vessel A. These chambers are provided with drop-nipples N, and to them are attached the sight-chainbers O, provided with openings P and glass tubes R, through which the drops of iiuid as they descend from nipples N may be observed. These devices are quite similar to the sight-feed glasses of the conventional locomotive-lubricator type. of the rate of feed is accomplished by means of a pointed spindle S, usual in such sightfeed devices. To the spindle is attached the lever T, which when up, as on the right side of the apparatus in Fig. 1, opens an outlet at the bottom of chamber M at U, the fluid passing from chamber A, through passages V and U, into the glass R and through the final drop nipple w to its destination. When the leverT is down, as on the left side The regulation IOO of the figure, the feed stops. The regulation is effected by moving the nut X up or down the threaded neck of chamber M. When nut X is moved upward, the tensionvof the spring Y is relaxed and the spindle S will move upward with nut X. When nut X is moved downward, the spring Y is compressed and presses against the collar Z of spindle S, pressing the latter downward.

To the top of tube I is secured the metallic bottom I) of a second glass vessel a, provided also with an upper metallic cap d, containing an opening f. A rotating cap g (similar to the cap G, already described) with an open ing L in it opens or closes a filler-opening, according as these openings f and 7i register or not. The fluid-tight joint between glass a and its metallic base and top is made by screwing the lock-nut k tight against the nipple Z of cap g, which tightens the glass on the cork washers c and e in similar manner as already described with reference to the lower glass A. A tube y', screwed into the metallic base b, passes through glass aand caps d and g, which tube is provided with an opening i), through which the fluid from vessel a, passes to a valve-controlled opening u in the base b, which communicates with the tube I. The valve which controls the opening u is part of a spindle s, to which is attached lever t, which, in conjunction with nut :c and spring y, effects the regulation of the rate of speed from vessel a in the same manner as do the regulating-valves for vessel A, already described. The fluid from vessel a passes down through tube y' and opening a into tube I, and down through that tube to a nipple n in the bottom B, and from that nipple through a sight-glass r, and finally through nipple w to its destination. Manifestly there is no communication whatever in this construction between the lower vessel andthe tube I, which serves as a conduit to carry off the contents of the upper vessel.

It is evident that changes in the construction of this apparatus may be made without departing from the nature of the invention. For example, the regulating apparatus of the upper vessel a may be dispensed with and the lower end of tube I may communicate with a T-iitting B, screwed into the bottom B, as shown in Fig. 3, into the ends of which T-fitting chambers M', similar to chambers M, Fig. 1, may be screwed, each being provided with the regulating feature already described for its feedoutlet. In this case the vessel a will simply serve as a reservoir to supply with fluid the chambers hf The bottom B of the chamber A is provided with drop-nipples w (oneof which is indicated in Fig. 3) and devices connecting the same to said bottom similar in function and purpose to those already described in connection with Fig. 1. It is also evident that additional chambers may be added to chambers M, as well as M', if more than two outlets are to be fed from either of the vessels A and a. Such modification for the lower vessel A is shown in Fig. 2, M2 representing additional chambers attached to chambers M, forming four feed-outlets from vessel A.

In all of these forms of apparatus it will be noticed that the vessels are superposed and that the conduit for the discharge of the contents of the upper vessel while it passes through has no communication whatever with the interior of the lower vessel, the contents of the vessels being thus kept wholly separate from each other.

Having described my improvements and the best way now known to me of carrying the same into practical effect, I state, in conclusion, that I do not limit myself to the structural details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of my invention but Vhat I claim herein as new, and desire to secure by Letters Patent, is as follows:

In a multiple drop-feed apparatus, a plurality of distinct and separate non-communicating superposed liquid-containing vessels, a discharge-tube leading from the upper vessel down through the lower vessel,

separate and distinct feed devices for the contents of each vessel, and regulatingvalves for the several feeds, substantially as hereinbefore set forth.

In testimony whereof I affix my signature in presence of two witnesses.
